I just picked up a 2000 S-Type with 70k miles. The last few days I noticed the radiator fans coming on more frequently after the car was shut off. I do not drive the car more than 10 miles a day at regular city speeds (35-45 mph). It will be running fine than quickly the engine temperature will move up to the red zone and the High Engine Temperature Warning comes up on the dash. Just as quick as it heats up the temperature will go back down. The radiator cooling fans seem to run at all times now. I have checked all the fluids and they are at normal levels. Am am thinking it is related to the thermostat but I am not sure. I live in a small town the nearest Jag dealership is 80-100 miles away. Any imput to help diagnose the problem would be appreciated.[color=darkred:3dfb65c29d][/color:3dfb65c29d][color=darkred:3dfb65c29d][/color:3dfb65c29d][color=darkred:3dfb65c29d][/color:3dfb65c29d][color=darkred:3dfb65c29d][/color:3dfb65c29d][color=darkred:3dfb65c29d][/color:3dfb65c29d][color=darkred:3dfb65c29d][/color:3dfb65c29d][color=darkred:3dfb65c29d][/color:3dfb65c29d][color=darkred:3dfb65c29d][/color:3dfb65c29d][color=darkred:3dfb65c29d][/color:3dfb65c29d][color=darkred:3dfb65c29d][/color:3dfb65c29d][color=darkred:3dfb65c29d][/color:3dfb65c29d][color=darkred:3dfb65c29d][/color:3dfb65c29d]

if the car has a v-8 in it you have to check the water pump.they are known for the inpellers breaking off. also the thermostat will stick. replace both and you should be ok. but when filling with coolant you will have to take the cap off the top off the thermostat housing as you fill so the air willl come out

Suggested Repair

Replace the thermostat and inspect or replace the water pump, since V8 impellers are known to break off. When refilling coolant, remove the cap on top of the thermostat housing so trapped air can escape.

Conversation Summary

The owner of a 2000 Jaguar S-Type 4.0 V8 reports intermittent overheating, temperature spikes into the red zone, and cooling fans running frequently or constantly despite normal fluid levels. Experts recommend replacing a sticking thermostat and checking the water pump for a failed impeller, then bleeding air from the thermostat housing when refilling coolant.
